EXHALATION MEASURING METHOD, EXHALATION MEASURING MODULE AND MOBILE DEVICE HAVING THE SAME

The invention discloses an exhalation measuring module, which may comprise a housing, a turbine and an electromagnetic converter. The housing may be formed with a receiving space connecting to an inlet and an outlet for passing an exhalation flow from the inlet to the outlet. The turbine may comprise a plurality of magnetic vanes, which are capable of rotation under the exhalation flow. The electromagnetic converter, positioned near the turbine, may generate electrical signals representing rotational motion of the magnetic vanes. The electrical signal may be outputted by the electromagnetic converter for estimating volume of an exhalation. 本发明公开了一种呼气测量模块，其可包括一壳体、一涡轮机和一电磁转换器。该壳体可以形成有一容置空间，该容置空间连接到一入口和一出口，用于使呼出气流从该入口流到该出口。该涡轮机可包括多个磁性叶片，其能够在呼出气流下旋转。定位于涡轮机附近的该电磁转换器可以产生表示磁性叶片的旋转运动的电信号。由该电磁转换器输出的该电信号可以用以评估呼气量。
